This invention relates to new and useful improvements in machines andhas particular although not necessarily exclusive relation to millingmachines.

The objects and advantages of the invention will become apparent from aconsideration of the following detailed description taken in connectionwith the accompanying drawings wherein satisfactory embodiments of theinvention are shown. However, it is to be understood that the inventionis not limited to the details disclosed but includes all such variationsand modifications as fall within the spirit of the invention and thescope of the appended claims.

In the drawings:

Fig. 1 is a perspective view of a milling machine constructed inaccordance with the teaching of the invention;

Fig. 2 is a side elevational view thereof on a somewhat larger scale andwith parts broken away to show details;

Fig. 3 is a longitudinal sec ional view taken substantially along theplane of the line 3-3 of Fig. but with the indexing yoke shown 120degrees out of position;

Fig. 4 is a vertical transverse sectional view taken substantially alongthe plane of the line 4-4 of Fig. 2;

Fig. 5 is a horizontal sectional view taken sub stantially along theplane of the line 5-4; of Fig. 3;

Fig. 6 is a vertical sectional view on an enlarged scale takensubstantially along the plane of the line 65 of Fig. 3;

Fig. '7 section on a larger scale, of the forward portion of Fig. 5 butwith certain turret carried parts omitted;

Fig. 8 is a sectional view on a larger scale through the work carryingturret of the machine;

Fig. 9 is a detail sectional view on a large scale, the view being takenas along the plane of the line 9--9 of 3 but with parts omitted;

Fig. 10 is a detail sectional view on an enlarged scale through theindexing plunger and adjacent yoke structure;

Fig. 11 is a detail sectional view on an enlarged scale showing themeans for locking the tool spindle quill in adjusted position;

Fig. 12 is a top plan view of the ejector cam of the machine of theinvention;

Fig. 13 is a side elevational view of such cam;

Fig. 34 is a top plan view of the clamping finger lifting cam of themachine;

Fig. 15 is a side elevational view of such cam;

is a view partly in plan and partly in Fig. 16 is a plan viewillustrating a tion of the turret structure;

Fig. 17 is a vertical sectional view taken as along the plane of theline l'l-l'| of Fig. 16;

Fig. 18 is a horizontal sectional view on an enlarged scale taken asalong the plane of the line I8-I8 of Fig. 1'7;

Fig. 19 is a further enlarged vertical sectional view through one of thework holding means of the turret;

Fig. 20 is a view similar to Fig. 16 but showing a further slightmodification;

Fig. 21 is a horizontal sectional view taken as modificaalong the planeof 'the line 2l--2l of Fig. 23;

Fig. 22 is a vertical sectional view taken as along the plane of theline'22--22 of Fig. 20;

Fig. 23 is an enlarged vertical sectional view through one of the Workholding means of the turret;

Fig. 24 is a longitudinal sectional view through the forward portion ofa machine equipped with a further modification of turret and having ahorizontal work spindle;

Fig. 25 is a view looking into the machine of Fig. 24- from the forwardend thereof the turret being omitted and the tool spindle being shown insection;

Figure 26 is a sectional View on a larger scale, through the work clampand a portion of the turret at the work cutting station of the machine;

Fig. 2'? is a plan view of the clamping element or dog of Figs. 24through 26;

Fig. 28 is a side elevational view of a modified form of work clamp ordog, a part being broken away to show inner construction;

Fig. 29 is a top plan view of 'the dog of Fig. 28;

Fig. 30 is a view of the front end portion of a machine equipped with amodified construction of tool head for mounting two tool spindles, thetool head being shown in horizontal section and other parts being shownin top plan;

Fig. 31 is a front elevational view of the tool head of Fig. 30; and

Fig. 32 is a side elevational view of such tool head but on a largerscale.

Referring in detail to the drawings and at first more particularly tothe form of the invention shown in Figs. 1 through 15, the machine ofthe invention is herein disclosed as a milling machine but includesfeatures finding application in other types of automatic machines.Generally my machine comprises a base Hi, a bed H on said base, ahorizontal tool-head carrying slide l2 on said bed, and a work carryingtur-
